Purchasing new Faction vanities after changing Factions

I have a former Shadow Lodge character that moved to Andoran faction after the closing of the Shadow Lodge.

Can I purchase Andoran vanities that are based on fame using my total from both Shadow Lodge and Andoran or must I keep separate fame scores and wait to purchase once I have achieved that much fame just with Andoran?

I'm thinking that since fame is cumulative, I use my total from both.

Total Fame is total Fame, even if you switched factions.

The only thing I know of that uses faction-specific Fame is the Year of the Waking Rune boon that just came out, and that explicitly covers how to handle faction in multiple factions.

As a roleplaying choice, my former Shadow Lodge barbarian is going to wait a few scenarios before taking the "Ulfen Guard" Taldor vanity. He's currently on "probation" and has to prove his new loyalties are genuine (they're not, by the way).

My former Lantern Lodge ninja, who obtained the title of "Master" before heading to Taldor, might just go ahead and pick up a Taldan noble title as well. And since Taldor seems to possibly have been on the bubble in Season 4 (at least, Mike seemed to indicate that in another thread), maybe she'll end up somewhere else next year. I wonder how many titles and/or 40 Fame faction vanities she can collect.
