impossible to autogenerate relations between tables in different schemas

### Is your proposal related to a problem?
YES

The "track all" relations funcitonality (in the data section) is not able to automatically generate relations from tables in different db schema.
it whouldn't be a problem (it is possible to generate them manually) but the procedure doesn't continue to generate those relation it can generate correctly. it abort the creation and show the error message.
Should be usefull to have a "skip error" option during this phase.
Optionally should be useful to extend the "Untracked foreingn-key relation" list, to the tracked ones as well, to better identify some relations that need to be manually modified!

thanks

Start in the Data section's “track all” relations flow and reproduce the failure with tables in different database schemas. Trace how automatic relation generation handles an error and compare it with the manually generated relations path. Done means the process can continue past an unsupported relation and clearly identifies relations that require manual changes.
