If I understand correctly the problem, it's already supported. For example, it's used in these rules:

apkmirror.com#%#//scriptlet('abort-on-stack-trace', 'document.querySelectorAll', '/Object\.visibleEl[\s\S]*?onload|Object\.vE/')
sotwe.com#%#//scriptlet('abort-on-stack-trace', 'String.fromCharCode', '/Array\.map[\s\S]*?\[Symbol\.replace\][\s\S]*?String\.replace/')
