I took another approach and posed my question to Affinity Support by email directly. Immediately the next day I receive an email informing me "Unfortunately there is no way to do what you are looking for at the moment in Affinity Photo." Upon receiving I asked for an ETA - silence. Apparently, I must keep LR in my tool bag. It would nice to a have formal request process for functionality enhancements from the Affinity user base to Affinity; and transparency from Affinity on future deliverables. 
 

I agree (in more restrained language) with @doolderboy — it's weird that after 3½ years the feature isn't there and there isn't even an ETA or a reason why not. Surely lots of users, probably most, have cameras that need the same RAW adjustments over and over? Not to mention that all the images from a shoot under fluorescent lighting… and so on.
Could we ask for a 
Yes, we'll add it [when?] or No, it's not on the cards [why?]

Yep. I run a specific noise filter via DXO and can easily do an entire shoot with that software. But with Affinity I have to do one at a time, which is why I don't use Affinity any more.
 

Hey Pink Panther,
An attempt at fixing the HSL crash was made in the beta which you can install from here:
I must clarify though that we were unable to reproduce it internally so if you still get the crash, can you let me know and also provide a crash report. 
@randomjames can you also give it a try  

+1 For this feature!
Just waiting for that! :D

I'd like to add a +1 to this thread.
I want to start using Affinity Photo for my complete workflow for photogrammetry, but i really need to be able to apply Develop Persona presets to a batch of multiple images (often 300+).
