Yes, make it as easy as possible so it can be part of every pre-flight.
I have seen gascolators with extension plumbing to position the drain valve accessible thru the air exhaust ramp- don’t like this because of more potential for leaks & in the end you get dirty & a crook’d neck getting the fuel sample.
I’ve seen gascolators with complicated remote valve actuators (cables, leavers & such) don’t trust them to not leak, & definitely would not be good idea with any FI applications.
Simple vertical drain thru an access hole is my choice. I mount gascolators on a sturdy firewall bracket (& reinforced firewall doubler) that offsets the gascolator forward so the sampling cup will clear the lower engine mount cross bar. My preference is to mount it just high enough so the bottom of the drain valve clears the inside of the fiberglass cowl so no chance valve would be damaged or snagged in any way. I drill the hole thru the cowl barely larger than the sampling cup (or screw driver) you will be using. This way the hole guides the cup up to the valve without you having to get upside down to aim it.
Hope this helps
Maintain lots, upgraded & repaired some, modified more, rebuild a few, & built 4 of 'em
