Is it possible to back up a non-precision approach using an ILS?

[ILS26L]

So I have a charted visual which I have created and placed into the nav database for the aircraft. It's the FMS Bridge Visual for 28R at KSFO. I want to select this approach while also tuning the ILS in the NAVAID page and intercept the localizer as I fly towards the final waypoint of the approach. 

This can be done in the iFly 737 MAX.

Can it be done in the A350? I tried it, but I never received the ILS signal. Upon pressing the LS button, the PFD showed 'FLS' even though I have correctly entered the ILS info on the NAVAID page. 

Is this not possible on the A350 or Airbus in general? Or am I doing something wrong?

@Eddie - from what I gather, this should be possible on any Airbus aircraft. If you select any non-precision approach, like an RNAV for example, you should be able to tune the ILS in the NAVAIDS page and intercept it even if you have not actually selected the ILS approach. However, this is not possible on the iniBuilds A350. The PFD will be in FLS mode instead of ILS if you select the LS button, which is not right.

Could this be looked at by the team?

I've comfirmed that this works with the Fenix A320 as well.

This needs to be implemented in the A350 too.
