How do I make the AEL button keep the exposure after I release the button?

Hi, 

Recently I bought the X100V camera and I couldn't be happier. I'm trying to dial in my preferred settings. Currently I shoot in manual focus mode most of the time, with autofocus set on pressing the back scroll button since I prefer focusing on the center and then re-compositing. 

However, I also have the 'photometry' setting set on 'spot' so I can quickly adjust exposure, so I can expose for shadows or highlights quickly.

Now, when I point to an area to expose to, I have to hold my AEL button to keep that exposure. Would it be possible to keep this exposure with one press and then releasing it? Because then I would be able to re-adjust my focus if need be, right now I have to focus > expose > shoot which is a lot less flexible.

Put the lock mode on “Switch” instead of “Press”.
