[FEATURE REQUEST] Template Path Autocomplete

[joshmedeski]

Is your feature request related to a problem? Please describe. Sometimes I mistype my "Template Path" and it takes me longer than I expect it to as there is no guidance while typing.

Describe the solution you'd like It would be more efficient if we could leverage auto-complete to select a "Template Path".

Additional context

• The "Folder path" has auto-complete, so something similar for "Template Path" would be perfect
• If the "Template Path" doesn't point to a valid file, it would be helpful to see an error message immediately
• My path is rather long, so making it the full-width of the modal would also be helpful (similar to "File name:" and "Folder path")
