Broadcasting: Can i specify my own date schedule?

All,

In the BI broadcasting area you can select the date like daily, weekly, monthly. Is it possible to add a customized variant to this selections?

I like to start broadcasting on the 6th workingday of each month ( saturday & sunday excluded) so the total number of days of each month is different.

In the source system (R3) we make use of a factory calendar.

Any options?

Many thanks,

Tom Hardeman
