Entity using records from other Entities

[chrisjiang]

Hi the magic development team, In real business activity we sometimes need to do the following:

Organize an event and invite people to participate. And of course some of the invitees are already in the Contacts Entity. We need to come up with a list which can be printed out.

Currently the Marketing list function does not support Printing and we can not see from the Contacts entity who participated in what (activities).

Is it possible to create a new entity and allow it to create records by selecting from other entities? For example, when we have a event we can create an entity and then created records by selecting contacts from the Contacts entity?

Thanks.
