Please allow for import of holidays, Place Holders, Disciplines, Roles, Locations and custom fields into resource management. Basically all fields that do not already have an import/export. It takes too long to key these things. Also if I set holidays and the values in smartsheet this should have synced up upon import.
If you want to provided economies of scale to users as their businesses grow and remove the complexity of use rating for SMartsheet this is an easy way to do it. I hope you put it on the roadmap. THe same features of update new/changed records would be ideal
