Is "forward-search" also possible case insensitive?

fo and rev commands take a REGEX, with escaping like

\d\+\s*\(SOME\|WORD\)

can we also search case-insensitive directly or is this only possible
with character sets?

\d\+\s*\([sS][oO][mM][eE]\|[wW][oO][rR][dD]\)

it would be nice to be able to specify a case-modifier
