Charge groups seperation Add on

We have a question regarding the set up of an Add on with different charge groups. 

We would like to create a package (one add-on) which includes multiple extra's from different departments. For example a bottle of cava and a late check-out. The cava is for F&B and the Late check-out is for rooms. We see that we can only create this package for one charge group. In lot's of systems we have worked with we were able to devide this however we see in stayntouch that this is not possible. 

Would be nice if this is something that can be created.
