Value data type structure


I wanted to implement this thing: the value of a data type structure is possible to set the value of a tag?
Because we wanted it that value was taken from the database and then deploy it with a tag that makes a select query and then insert it into value.

I insert a picture and instead of the value DB130 there should be the name of a tag referenced.


As far as I know this isn’t possible. Anyone know any different?
