Create link feature within select field?

Hi,
I need to create a link next to a select field in order to make possible to user to fast insert the missing master data related to a select field. Once inserted the new master data row I want that user come back in the same field and choose from the select data the new one .
Scriptcase by default insert the Edit button close to field but in my case I got lot of fields in form and it’s too large to have this button on all select fields I have there.
My idea was to use “+” instead but the issue is the following one.
If I change the text (on Application language) of “Edit” then in all other parts of application I will have the issue of “+” instead of Edit .
I’m stuck here and I don’t know how to fix it
