[Feature Request]: Additional checks from the Filter Transform to multiple copies transforms

### What would you like to happen?

At the moment there is a check that does not allow you to specify multiple copies of a transform directly after a filter transform which makes sense. However if your transform is already set to multiple copies you are able to create a hop FROM a filter transform to this multiple copies transform. You can also split a hop between a filter and a third transform with another transform set to multiple copies.

Component: Transforms

Start by reproducing the filter-to-multiple-copies connections described in the issue and reviewing the three linked screenshots. Trace the existing check that blocks multiple copies directly after a filter, then compare it with the additional connection paths described. Done means the invalid paths are consistently rejected without breaking valid transform connections.
