When duplicating a solution, you can choose to duplicate without records and open comments. However you can't duplicate with a choice to not have linked record fields.
I don't mind if the solution has several apps and they are internally connected. But it does cause problems when I have linked record fields to other solutions. Not just with the Linked record fields, but with lookups and formulas.
It can be sloppy duplicating a solution and having the linked records fields within connected to outside apps in the new solution.
I find myself copying the solution to another smartsuite account. Then recopying it back into my account to make sure it is clean without the linked record fields. Then removing or adjusting the lookup fields and formulas.
It would be nice to have a checkbox to unselect linked record fields when duplicating a solution.
