Child (Pillion) Places / Age(s) & Ranges

Offering Motorbike tours we obviously don't encourage children, consequently able to rename Adult places to Rider and Child places to Pillion, as they're around 2/3 of Rider rate, never arrive without a rider and room occupancy can be 2 Riders or 1 rider & pillion, piece of cake. Maximum age for Pillions was 99 but now limited to 17 in the Solidres Options, I was relieved to see it could be altered in each property, but when check there, maximum age is still 17.

I suppose the only answer is to set both to '1' although I can see the emails arriving "oh, you're going to treat us like babies" or similar, is there any way I can auto-select/hide the child /pillion age in our booking forms please
