not as far as I know. I have the same problem. I have created a Liberty system: Florida and create everything for it, a separate name, a new info card for the system. etc.
But when you enter the system it keeps saying Florida system, Rheinland space. Perhaps there is a file somewhere that still needs to be edited.
Also what I can't seem to do is getting an automatic update for my own created infocards.
According to a system's ini file, a base has 2 infocards. One is mentioned in the ini file and the other not. If you take for example Fort Bush:
ids_info = 65755 is the one in the ini file
looking that up:
<?xml version="1.0" encoding="UTF-16"?><RDL><PUSH/><TEXT>CLASS: Goliath</TEXT><PARA/><TEXT>GRAVITY: Complete</TEXT><PARA/><TEXT>DOCKING: Yes</TEXT><PARA/><TEXT>AMENITIES: Yes </TEXT><PARA/><TEXT>POPULATION: 5K</TEXT><PARA/><POP/></RDL>
So that's basically just the info you see when you are near the base, but never docked there.
Once docked it adds the information that is on the infocard 65756:
<?xml version="1.0" encoding="UTF-16"?><RDL><PUSH/><TEXT>Ft. Bush was one of the earliest outposts established during the settlement of Liberty. As Liberty expanded, Fort Bush became a popular jumping-off point for any number of wild business ventures as explorers set out to make their fortunes among the stars. Today Ft. Bush provides a haven for traders from all over Sirius who have business to conduct in Liberty. A branch of Liberty Police, Inc. (LPI) headquartered aboard the station helps maintain the peace necessary to a free economy by suppressing pirate activity in the debris fields and administrating automated weapons platforms that defend the nearby Trade Lane junction.</TEXT><PARA/><POP/></RDL>
I can't seem to get that working in my own created system as well
