Hello @tolstovaulia257 ,

There is a default functionality similar to your request. You could see an “Add formula” button near the editor with all available formulas:

When formula is selected in the editor, the popup with formula parameters suggestions is also shown.

If you need something different, could you describe your request in more details?
