How to remove repetitive parameters in class methods?

I've got a class implementing an interface, with some 15 methods. The methods all need a string SectorId that is passed onward to another service, which make the class looks like this:

public class A: IA {
 public string A1(string sectorId, ....) => _otherService.B1(sectorId, ....);
 public string A2(string sectorId, ....) => _otherService.B2(sectorId, ....);
 public string A3(string sectorId, ....) => _otherService.B2(sectorId, ....);
 public string A4(string sectorId, ....) => _otherService.B2(sectorId, ....);
 ...
}

Is it possible to get rid of the repetitive string sectorId while still achieving the same objective? This class handles webAPI calls and is dependency injected to the controller which calls it.

I thought of having the sectorId as a constructor initialized parameter, but that would mean either not using the class as a DI singleton and, instead, scoping it to the request or not using DI altogether and just initializing it on every request. Is there a better way to handle this?
