Save aditional info in dspx

Hi everyone! Im absolutely new in DotSpatial use and i have a question wich i have not found in the discussions.

I would like to save the name of the "master" column of each layer to identify each layer item in my own database.

I mean, for example in a point layer representing cities, the ".shp" master column i would use is the ZIP code. So when i click on a point i would know that ZIP code column is the one i need, and with its value, i could access to my own database and get any useful data i need.

Is there any way to save in project this "master column" value for each project layer
