I just made these blocks in BYOB. They are:
<(text) contains (text)>
(letter (number) to (number) of (text))
Download As A BYOB Sprite
It's slow, and runs best in turbo mode.
Note: The <(text) contains (text)> block requires the (letter (number) to (number) of (text)) block. That's why I didn't have them as separate sprites.
P.S. Does this go in requests or another forum topic besides this one? I've been having some confusion about placement of forum topics lately.

Awesome!
You could submit these to the Local Block Library.

Letter () to () of [] can be faster with recursion. Try
Letter (a) to (b) of [s] if (a) = (b) report (letter (a) of [s]) else report (join[letter (a) of [s]][letters (a+1) to (b) of [s]])
