Your friend should respond pleading NG to all offences.
In the 'mitigation' section, she can indicate that she will be willing to plead G to the speeding if the FTF charges are dropped. Since Covid, some courts have been receptive to that.
Failing that, as M60NJP has said, do the deal on the day, but with the prosecutor, not the clerk! She should get there early and ask an usher to point her towards the prosecutor dealing with the motoring cases.
