Google Sheets - Get Cell, Sheet Name Issue

What are you trying to achieve?

Get a sheet dynamically with increments to extract data.

Steps taken so far

I’ve a done a workflow where it would take data from one Google Sheets file with multiple sheets from a specific cell. For example, I want Cell D4 from all the sheets that are labeled
Sheet 1
Sheet 2
Sheet 3
Sheet 4 … etc.

and take them to a different Sheets file using the same increments.

I’ve done it all and it works, except the Get Cell Function which only allows me to select a single sheet from a drop down menu. How can I add a custom input with strings and number the way I’ve done with the Update Cell Function, if it does not give the function.
