Allow creating a new row when picking a "link to table" item
Oftentimes when using the "link to table" field, the row you want to link does not yet exist. In the picker, there could be a plus symbol at the bottom to create a new row in the linked table, or there could be the option to create a new row when the "search rows" function produces zero results. This would allow users to create a row in another table in place, maybe as just a draft, and fill in the details later.
