Allow Friend Support to be Any

Firstly, thank you Mathew Sachin for FGA.

I just need any friend support that can NP.

Mode "First" doesn't work as a non friend support may be First.

Mode "Friend" requires you to list out all your friends

Mode "Preferred" does have a "Friend Only" switch, but you will need to specify a preferred servant or CE.

Any servant would do, and its easier to configure CE ingame, as you don't need to make images and then delete them later to reduce clutter.

Therefore, I would like the feature to get any friend support (that can NP)

This can be easily achieved by either removing the popup failsafe when mode "Preferred" runs without specifying preferred servant or CE/option to leave fields as null/"First" mode gets a "Friend Only" Switch

Thank you

Start by tracing how the First, Friend, and Preferred support modes select servants and trigger the popup failsafe. Compare the requested Friend Only behavior with the existing Preferred and Friend options. Done means a user can select any friend support capable of NP without listing every friend or configuring a preferred servant or CE.
