power automate excel template

All,

I am sure every one like the power automate capabilities with word template files. First we create a word file with several "Plain Text Content Control" from with in Developer Tab -> Design Mode. This is a lovely feature (Unfortunately a Premium Feature). While the use of word file is premium, not sure if you guys noticed that the Excel file is not a premium. 

Does any of you guys know of a way to use excel file to create  "Plain Text Content Control" from with in Developer Tab -> Design Mode

Possible?
