Quick Create will not work after making a field mandatory

We need to make a customfield mandatory.

Once that is done, Quick Create will no longer work from the RT home page because there is no access to set that customfield.

How does one get around this?

This is what prompted my desperate search to find out how to create a customfield and imbed it into the QuickCreate portlet.

I have seen this asked many times and I have searched for and answer but can not find one.
