When viewing entities in Console (apps, instances, versions, experiments, etc.) the backend returns the most recently updated 50 with a pagination mechanism to view more beyond that.
This same approach is used to prefill options for select dropdowns, but there was no way to load more options if the one you want was not included in the first 50 returned.
To address this, a new load more button has been added at the end of the select dropdowns that will continue to load more entities until the one that is required is found. This functionality has been added to the Versions select on the create and edit instance views, and the the Inputs select on the create input set view.
