Change Assigned to font

Can the color scheme, background or font be changed in the synchro field app when users try to submit a form for review. When they submit a form for review it prompts them to assign a recipient for review, but the default image appears to be greyed out or locked even though it can be accessed. There are other areas that look similar that are locked when the forms are assigned between users. This can be confusing to new users. Please see attachment “Synchro Field Issue – Assigning form for review” above.
