Automatic markers for bars/measures

I'd like to use the application to practice a specific section of an audio file. I know I can set markers manually for the start and end of the section, but I find it fiddly, especially since the Android app doesn't appear to let you zoom in.

I was thinking that a handy feature might be to allow the user to specify the start of the song and end of the song and specify how many bars/measures were in the song, and then the app would automatically create markers (numbered from 1 to the number of bars/measures).

Once created, this would allow the user to specify which bars/measures they wanted to repeat.

Obviously this wouldn't necessary give the user the exact bar/measure position, but would give them a starting point that they could fine-tune
