Dave, you show your ignorance...again. I know you're not interested, but there are grammatical guidelines for when to and when not to hyphenate compound adjectives. It doesn't matter if the compound word is not found in the dictionary. That's when the guidelines are used.
As the source below states:
"[U]se hyphenation...to join a word to a past participle to create a single adjective preceding the noun it modifies: 'a well-intentioned plan,' for example, or 'a horseshoe-shaped bar.' Be aware, however, that we do not hyphenate these same phrases when they FOLLOW the nouns they modify:
--This is a government-mandated program.
--The program is government mandated.
--She is a well-respected student.
--She is well respected as a teacher.
Another basic rule is that we never hyphenate compounds that are created with '-ly' adverbs, even when they PRECEDE the nouns they modify: 'a fully developed plan,' for example, or 'a nationally certified teacher.' Here are more examples:
--We sent in heavily fortified troops.
--The troops were heavily fortified.
--All newly employed nurses must be evaluated regularly.
--All the nurses on the eighth floor are newly employed.
--A beautifully designed room can be both relaxing and invigorating.
--The living room is beautifully designed."
