We have now published v2026.2.2-beta.0 which allows adding points when a constraint with incremental=true is violated during geotrace/shape entry. You can learn more about beta testing Collect here.
We don't typically do betas for point releases but we decided to this time because it changes the behavior to recently-released functionality in a subtle way. If you've started using incremental=true, please give it a try and let us know if you have any feedback.
