Is using multiple withMethods() in a single SignalStore considered a bad practice?

[MaltePetersen]

Hello,
Is using multiple withMethods() in a single SignalStore considered bad practice? I started doing this to reuse already defined methods in new ones, but it seems to make the code harder to read over time. Is there a better approach? Here is a example, where I first define the method getPremiumCustomers and always call that method after a new PremiumCustomer is saved in the savePremiumCustomers method.

export const LeadTimeConfigStore = signalStore(
  withState(initialState),
  withMethods((store, leadTimeConfigAPIService = inject(LeadTimeConfigAPIService)) => ({
    getPremiumCustomers: rxMethod<string>(
      pipe(
        debounceTime(300),
        distinctUntilChanged(),
        tap((query) => patchState(store, { currentDeliveryArea: query, isLoading: true })),
        switchMap((query) => {
          return leadTimeConfigAPIService.getGroupACustomers(query).pipe(
            tap({
              next: (value) => {
                patchState(store, { currentPremiumCustomers: value, isLoading: false });
              },
              error: (err) => {
                patchState(store, { isLoading: false });
                console.error(err);
              },
            })
          );
        })
      )
    ),
  withMethods(
    (
      store,
      leadTimeConfigAPIService = inject(LeadTimeConfigAPIService),
      notificationService = inject(NotificationService)
    ) => ({
      savePremiumCustomers: rxMethod<void>(
        pipe(
          switchMap(() => {
            const deliveryArea = store.currentDeliveryArea();
            const premiumCustomersIds = store.currentPremiumCustomers().map((customer) => customer.id);
            if (deliveryArea !== null) {
              return leadTimeConfigAPIService.putSavePremiumCustomers(deliveryArea, premiumCustomersIds).pipe(
                tap(() => {
                  store.getPremiumCustomers(query.deliveryArea);
                })
              );
            }
            throw Error('deliveryArea can not be null');
          })
        )
      ),
    })
  )
);
