^^^^^ What matters when defning the type of rhyme is the last vowel accented and all the consonants that follow...

What you're talking about is multi-syllable rhyming...that can be done rhyming 1 words with many syllables, or 2-or-more words in a rhyme series

Multisyllables meaning 2 or more, obviously...I typically like to rhyme 3-4 syllable words or phrases in that way...But, in some cases, I'll rhyme 2 syllables in a sequence

Eg...In a bold flash, I put the cold flask to my own past

Techincally flash and flask are assonance...not true or "perfect"...but, there's nothing that says all the syllables have to be either true or assoance...they can be a combination in my opinion

Just, play around with your own style...
