Macro for data tables in financial model slowing down excel

Hello,

I have a large financial model with 4 P&L's and data tables next to them with two variables. The data tables seem to slow down the model and crashes it on some occasions, even when calculation options are set to Manual or "except data tables". I would, therefore, like to create two buttons with a macro attached to it:
- Load data table (I basically want my data table to be empty when opening and working on the file, so that I have full performance, then be able to load it)
- Delete data table (once I had a look at the data table and taken a screenshot, I want to delete it again to get full performance back)

Can someone help me with an existing code for this or an alternative solution? Unfortunately I am not allowed to share the file.

Thank you in advance!
