Is this a useful addition?

I added the following in my image: MAOptionDescription>>labels: aBlock "Set the labels for each option by evaluating the block." |labels| labels := Dictionary new. self options do: [:ea | labels at: ea put: (aBlock value: ea)]. self propertyAt: #labels put: labels. so that is is used like: descriptionProvider ^ (MASingleOptionDescription new) selectorAccessor: #provider; label: 'Staff'; reference: ALStaffMember description; options: ALStorage rootOrg staff; labels: [:ea | ea fullName]; priority: 20; yourself This is very helpful for me using SingleOptions that are pointing to dynamic lists; is there already a way to do this without modifying Magritte? - Brian
