Outboard FX Option in FX Rack

I would love to have the ability to send FX Rack inputs to outboard FX. For example, if I want a reverb or delay unit in Waves, and want control of how much I send an input, or group of inputs, to that Waves rack, and how much I hear the return, the only way to achieve that on dLive currently is to use up auxes, which can sometimes be a pain when there are not enough dedicated auxes and no more can be allocated. Is it possible to have a built-in FX Rack library option dedicated to “Outboard FX” that sends whatever is in that send to a specified output, then pulls the return in from a specified input? Yes, this could add a processed input to the board, but if it could be built into the return, that would be amazing. This uses up an FX rack to send to an outboard FX unit, whether Waves or physical, pulls that return in for easy control and organization, and saves auxes. Although auxes can work, I feel they take up space that could be dedicated within the FX rack if this feature is possible and available.
