Crowdin - Google Suite opportunities?

So, I know there’s a Google Drive integration, but as I see it will bring all files from Drive to Crowdin, and due to security reasons I don’t wish this. I’d like not to create a separate Drive with needed file but to select some files from Drive only. Like Sheets, mostly I work with Sheets. Is it possible?

I found a separate google spreadsheet integration, you can see it here, it’s free

Probably crowdin will do the same with other google products in future, like docs, presentations and other staff.
