tracker capture "tree"?

Hello all,
Is there any way in the tracker capture app to have users see the org unit tree that can be see on the computer - to choose a higher level org unit first and then see the lower org units? (Choose a region first, then see the list of districts in that region…) We have data collectors who are working in over 50 different districts, and since they are assigned at the district level, it is causing problems that they have to scroll through 50 districts each time.

Thank you!

Natalie
