If subjects require the same values (during the same shooting session), the solution is pretty simple. Don't complete the exposure file. That means you leave the exposure file open, input additional holder numbers, and reuse the exposure until you wish to close the file (press done). It's rather unfair to generalize your user experience as "bad" because the app was somehow inconvenient for you. I use ExpoDev and have since 2010. I highly recommend it to anyone wishing to obtain better, and more consistently made, negatives.

Still waiting for this feature to be updated. I no longer use BTZS because it is such a bad user experience having to start from scratch for every exposure. In fact it was the reason I posted the idea on the BTZS forum initially and now 2+ years later and a recent update and this feature still has not been added. Very disappointing.

This would address an important usability issue with the app. I often make multiple exposures tweaking just one or two parameters (e.g., with and without filters, etc.). Starting a new exposure from scratch is not efficient. Ideally, we could start a new exposure with any previous exposure settings as the start-up defaults.

This is a great idea. I ran into this situation in the field yesterday. This function would be very useful.
