I sometimes have to read from multiple readers. Is it possible to set the maximum features to read to ALL feature types? Not just all per reader? Related, is it possible to set the Search Envelop for ALL readers?

One way to do this is to create a published parameter and set this on all readers. Then you can change them al in one move.

Steps are:

• Click on the arrow next to the field in the (Feature)Reader.
• Choose User Parameter --> Create User Parameter...
• Go to other fields and Choose User Parameter --> Your created user parameter.
