Look into Inquire. I believe one choice is "member names" or somesuch. So
you can ask this of a whole Group of named Fields and get a List back,
suitable for piping into a SelectorList. However, there is some arbitrary
upper limit on the number of characters SelectorList can take (since it has
to display in the user interface), maybe about 2K, I think, so if the list
is too big you may get clipped.
Of course, you can step through the Series (if your Group of Fields is so
composed) with Sequencer, so the user never needs to specify the arbitrary
time. Just pull the time value out and display it in a Caption so they can
verify they are at the right time. To do this, you also use Inquire("member
name"), or if you assign time to a "time" Attribute of each Field, use
Attribute("time") to get it back as a value to pipe to Format (if it's
numeric to convert to string) or straight to Caption (if it's a string
already).
