Hi Viivi,
at the moment the best we can achieve is to use a flexible activity of 4 hours within the Work Plan shift. This wouldn't give a specific 4/4 hour split but it would schedule the 4hrs of Back Office at the best time to balance the on-queue demand.
There is a similar idea listed in the Ideas Portal, WESCH-I-325, please take a look and add your use case, comments and vote to help us best understand the challenge and prioritisation of future enhancements.
thanks,
Paul
