Hello,
in my big model I have no detected, that Indexes have been created in an other user than the original tab. This is due to the fact, that in both cards separate selections are possible.
I think, in most cases the index will be under the same user than the table itself.
I would propose, that the user/schmea from the general tab would be transferred to the Index tab. Therefore in the general tab could be a checkbox.
The drop down in the Indextab could be also exist, but swould show at default the selection from general tab and can separately selected, if checkbox is not checked.
Best regards
Linus
