QB Issue Resolution:

We have the same issue with group items in desktop.

the only way to control the group price is to include  a discount item that lowers the total price of the items (or increases it if you want)

create service type item, name it, link it to the sales income discount account, set the rate to a negative number, the amount you want the bundle sales price reduced by, and include it in the bundle
