Hello,
Yes, in order to achieve this you can add more package updates (for different products) in your
updates configuration project. Please keep in mind that when use this scenario it is recommended to use a
registry value search as detection criteria for your updates.
Also, please note that when use this scenario users will see the available updates for all products added in your updates configuration project (even when they don't have a previous version of a related product already installed).
Let us know if this helps, otherwise give us more details about what you want to achieve (maybe exemplify).
All the best,
Daniel
