Little Help Please

[Doolar]

I'm hope'n someone will get me pointed in the right direction here. I would like to make my resupply ships behave like the U-Tankers so if I need to resupply at these resupply ships, I won't lose my current patrol stats and start a new patrol from them. S.hie's readme states ….Also, you can only pseudo-dock at U-tankers, not at surface tankers (e.g. Brake), nor at land bases. You can still choose to dock in the old way, if you wish. If you want this mod to also work with surface tankers, these must be renamed e.g. from "Brake" into "U-Brake" in the campaign files.... I would like to pseudo-dock at these surface tankers, but I'm not sure where to find the tankers to rename. The be clear I would rename :
Max Albrecht to U-Max Albrecht
Bessel to U-Bessel
Thalia to U-Thalia
Corrientes to U-Corrientes
Charllote Schliemann to U-Charllote Schliemann
Brake to U-Brake
Maybe I'm not looking in the correct folders. Any assistence here would really be appreachated
