[REQUEST]: Add the ability to assign the same trait value to all plots (example date of collection).

[hkmanching]

Description

This was a request from a breeder Instead of navigating through each plot and assigning the same date over and over, I would like the ability to assign a date to all plots at once. This cannot be accomplished with the default trait easily because you would still have to change the default value for each date and navigate through plots to assign the value.

Several layers here but this can/should be added as an option when creating date traits.
