HELP! Cracked ABS Toilet Mounting Flange

Help! Hoping someone has some advice. While re-mounting toilet bowl on to ABS flange, I overtightened one of the attachment bolts and cracked the flange – the toilet will not attach securely on that side now. Because flange and pipe below it is ABS, they are cemented together. Any way to repair the flange WITHOUT having to replace a complete section of the pipe below it?? It’s fairly easy access to cut/remove old pipe and flange, and install new ones, but I’d rather not if another option is available!!
