Cross project hidden dependency

[Dactech]

Hi,
Is there any way to set up dependencies between projects without the processor task being shown on the gant chart?



e.g.
Project A is procurement with tasks showing arrival times for various items.

Project N is for commissioning of a specific section and installation can not commence until the equipment arrives
but there is no need to show (and print) the procurement task (just treat it as a hidden predecessor).

Thanks
