Question about steroid enemas

Hello, this is just a quick question about steroid enemas. My favorite enemas are the asacol/ salofalk enemas, where it automatically administers the correct dosage through the press of a button for you. However, the mesalazine enemas aren't quite doing the job right now, the steroid enemas were okay, however they never seemed to work properly as I never seemed to be able to administer them myself by filling up the applicator, I couldn't seem to get the correct amount of foam in, it just seems a bit too awkward for me to do.

So I was just wondering, is there a form of steroid enema that automatically administers the correct dose via the press of a button, like the mesalazine enemas?
