What's cool with templates is we can change them.
Here you are in your current index X. You need a template from a previous one, but not the entire thing.
While index X is open, save it as a template and name it something like 'almost.' Options>Save as Template.
Then go to Options>Load from Template which will list all available templates. Choose the one you need and look at the locators then. Make a note of them.
Go once again to Options>Load from Template and choose 'almost.' Then fix the locator formatting and Save it one more time with a name that makes sense to you.
Another thing I do sometimes is to open that previous index with the locators conforming to the way I need them just to see and make a note of those. No need then to do all this as I suggested above.
It's really not possible to look at the templates themselves -- just the effects they have on formatting.
You almost have it!
