Namaste Dean,

If you are a linux user,
Ibus-m17n would work just fine with IAST diacritics for all programs.

If I have to convert some small patches to specific transliteration, I write in Devanagari / SLP1 and get it converted at 
https://learnsanskrit.org/tools/sanscript . Hope this helps.

Can anyone recommend a web site or program that allows one to easily create diacritical marks in Romanized Sanskrit transliteration?

Thanks,

Dean
