If I understand you correctly, you are trying to make all the measures show Time Signature - right?

Measure Tool.

Select All.

Double-click on a selected measure.

The dialog box Measure Attributes appears, at the top saying “Measure Attributes for Measure (first measure) through (last measure)”.

Choose

Time Signature: Always Show

When you OK, all the measures will display Time Signature.

No sir, not all measures.  Just certain measures.  And I want to be able to do it quickly, without going through all the steps.  

For example, here is the etude I wrote this morning for my 7th grade band: https://drive.google.com/file/d/1ohykxIXTWrUFecGIiM_rJj5Ps9rULHru/view?usp=sharing

Justin Dickson,

I am not an expert on FinaleScript, but I suspect that the macro can be done as a FinaleScript script.

Then, run that script on the first measure of each etude.

You also need a macro for the final measure of each etude:

In the Measure Attributes, select {Hide Cautionary Clefs, Key and Time Signatures}.
