Add New Option To Rules In Zoho Form

Add New Option To Rules In Zoho Form

Hello,

Please add new options: FILLED, BLANK to the Rules in Zoho Form in addition to current, which IS, IS NOT, STARTS WITH, ENDS WITH. It's critically important options!

AN EXAMPLE: Need to create Rule that allows to SHOW / HIDE lower field if upper filed is FILLED or BLANK. 

How to do this, in case all existant options ruled only by logics IS, IS NOT, STARTS WITH, ENDS WITH are not relevant?

Please ADD THIS OPTIONS INTO Soho Form.

Thank you.
