Anyone trying to import grease pencil drawing into another grease pencil file:

Click File --&gt; Append
Select the Grease Pencil File you want to import --&gt;
A new menu of directories pops up, select COLLECTION --&gt;
A new list of collections pops up --&gt; select COLLECTION again.
Done, your Grease Pencil object should now be &quot;in&quot; another Grease Pencil canvas.
