We would like to be able to add values in a custom lookup definition without using the customizer.
We had found a solution via a query on the db which seemed to work, except that we realized that we were no longer able to create lookup values using the customizer. (The idea I had was that the customizer went to read the max(id) of the table somewhere but then by doing the insert it found the id already used by our insertion via query)
Have any of you ever done something like this successfully? The best thing would be to be able to do it with a rest call, but we can't really figure out how to do it
