allow unlimited number of values AND repeat ?

Issue Summary

first of all thanks for this module KarenS, this is amazing combined with calendar.
I got a dilemna though, concerning the edit mode ui.

some of my users need to enter tricky schedules (ymd hm) with repeating dates at different hours :

using the repeat option widget,
. they can easily add repeating events on a 6 months interval like every tuesday from 10am to 12am, between april and june,
. but they can't add friday from 2pm to 4pm in the same interval, since the additional fields cant be used in the case hours are different, only for days. (and I understand why I guess from concept and php point of view)
. and they cant add another date, since there's option to setup the max number of value.

using a widget with no repeat :
. they can add what they want, since I was able to setup the max. number of values to unlimited
. but if they need to schedule a repeating date over 6 month, this takes ages.

I agree (and I did actually), I can use several nodes with single repeating fields linked through views and relation ships arguments etc and display the events in one calendar.

but my not-so-geeks users rather like a simple mecanism to schedule, all in one node.

it would be handy to provide both the repeat and the 'more than one value' global features for date.
(but maybe I missed something if so please let me know.)
