Sync multiple computers to one Google drive account

I have several computers with data that need to be sync’ed. Is it possible to sync them to one Google drive account? Specifically, what I would like to do is as follows:

Insync directory of Computer A:
   /home/{usenameA}/InsyncA

Insync directory of Computer B:
   /home/{usenameB}/InsyncB

Insync directory of Computer C:
   /home/{usenameC}/InsyncC

...

Google drive directories:
/My Drive
    /InsyncA
    /InsyncB
    /InsyncC
    ...

@yltang Yes. This is possible with Insync. You need to use the add to Insync feature, however the default sync folder is the root folder of your Google Drive. Once synced, you need to move the files for folder to your desired location. Once moved, it will resume syncing to it’s current location.

If you have additional issues or concern, send us an email to support@insynchq.com

Thank you.

Based on roald’s solution (many thanks), I summarize the procedure as follows for people who might be interested.
Suppose there are two computers, A and B, that need to be sync’ed.

(1) Install Insync on A and B

(2) On A, use the “add to Insync” option to add the files/folders that need to be sync’ed.
(In nautilus: right click the file/folder --> Add to Insync --> Choose your google account. Insync will create a symlink copy inside the Insync folder.) For example, fileA is added to Insync:

A:
<somePathA>/fileA
~/Insync
    fileA

Google Drive:
fileA

(3) Create a new folder, InsyncA, and move fileA there:

A:
~/Insync
    /InsyncA
        fileA

Google Drive:
/InsyncA
    fileA

(4) Repeat Step 2 for B

B:
<somePathB>/fileB
~/Insync
    fileB

Google Drive:
/InsyncA
    fileA
fileB

A:
~/Insync
    /InsyncA
        fileA
    fileB

(5) Create a new folder, InsyncB, and move fileB there:

B:
~/Insync
    /InsyncA
        fileA
    /InsyncB
        fileB

Google Drive:
/InsyncA
    fileA
/InsyncB
    fileB

A:
~/Insync
    /InsyncA
        fileA
    /InsyncB
        fileB

(6) On A, set “Selective Sync” to exclude “InsyncB”. And on B, set “Selective Sync” to exclude “InsyncA”.

Google Drive:
/InsyncA
    fileA
/InsyncB
    fileB

A:
~/Insync
    /InsyncA
        fileA

B:
~/Insync
    /InsyncB
        fileB

From then on, all new files/folders should be added to InsyncA and InsyncB folder for A and B, respectively.
