Combining dropdown options with "Other" as option#310

Right now, wherever there is a dropdown (or multi/single select) item, we have to choose whether the user can choose from referencing a repeating item (e.g. Children), or a customized amount of choices that we create for them. However, it would be useful to reference a repeating item or pre-created choices, AND have the option of “Other”, so that they can either choose from these options, or write their own entries. On the builder side this would be a simple toggle button “include “other” button”.

Additionally, it would be practical to include multiple referenced repeating items and/or combination of written out choices + reference repeating items.

This would be the “perfect” question example:
Questions: “Who do you want to create a Power of Attorney for”
Choices:
Children (repeating item)
Child 1
Child 2
Child 3
Parents (repeating item)
Adult 1
Adult 2
Monica Geller (pre-written choice)
Chandler Bing (pre-written choice)
Other (“Other” button with text area opening every time it’s selected)
