I use free codes but I'm able to be extremely consistet with it so my field to finish still works perfectly. No one from our field crew can do that so I have them using a codelist I loaded into their DCs
if no one knows how to use codelist just edit the point id with the abbreviated description of the point observe then download the data in csv or any text file and edit the data using excel spreadsheet to correct the column by point id northings eastings code description. after editing you can import points to any software like liscad civil 3d sdrmap etc. be sure that the text format similar to that of pre defined text format of the software.
