Nemanja,

The Schematic Irrigation list is fixed per Preference Set. If you are looking to have the same list of Schematic Irrigation options in each project, then you simply need to be using the same Preference Set for each project. The reason there is no Import option is because the Preference Set is the standards that are there for each project that do not/should not change. If I am misunderstanding what you are looking for please let me know and we can go from there if needed.

Regards,

Thank you Jake,

I have added those categories to Preference Set. Unfortunately those made in separate Project could not be transferred to Preference Set.
