Our customers need new feature at Cross Site Lookup Selector - remember selected values on Form.
We have large forms.
When I fill many Lookup fields, and I forgot someone required, on trying to save the form are all lookup fields empty.
Therefore we need add feature - temporary save lookups on form to not loose selections after refresh the form.
I have some script for not multi lookup selector. The script at JS save the selection on form after change, but it do not work on multi and it is very complicated to do it for many forms.
