I use landmark and use additional plant records to include information about landscape areas such as seed mixes which then input into my schedules (worksheets). As these detailed soft and hard landscape drawings can get very heavy on larger sites (very painful for my work flow), I would like to split up the drawings into seperate files (eg. soft, hard, specific designed spaces) which I then reference as viewports into a drawing with the sheet layers and worksheets. This helps for a number of people to work on the project at once by splitting up the drawings in this way. This works well until I come to schedule the drawings and the records are not imported although landscape areas and plants are. Currently I have to combine my colleagues drawings before scheduling which is very time consuming and usually crashes.
It seems sensible that all data is available from referenced viewports.
