how do you get around this limitation??
Quite simply... you don't.

It is possible that your sheet has many blank rows that are unnecessarily adding to the row count. If you actually have a sheet with 36000 rows, then that is not something you put into ShartSheet (SS).
Rememer that SS is a collaboration platform, and not really a DB or spreadsheet program (though it does resemble the latter quite closely). Every system has limits, and SS has set theirs.
