Organize RewriteCond and RewriteRules in groups

[kornicameister]

If I understand Apache configuration correctly, RewriteCond or a lot of them are there to support when RewriteRule should happen. Would it make sense to provide have them grouped together?
Consider following example

RewriteCond ... [OR]
RewriteCond ... [OR]
RewriteRule ...

that outputs as something like:

rules: {
  '{rewrite_str}': [{conditions}]
}

not quite sure how to model conditions (AND and OR) but intention should be clear enough?
