Multiple workers question

Hi Nikola,
first of all thanks for a straight forward approach to build an appointment plugin. It’s good that you can create connections using a shortcode, but is there any chance of using multiple workers on one single service?
One example of use: a massage studio has 3 rooms and 2 masseurs. Some massages can be done only in one specific room and some massages include two masseurs.

My last question might be more appropriate – are you open for custom development? If yes, at which rates?

thanks
vk
