Improve Target API for Recommendations

[#1]

I’m trying to get # of 'In Stock' & 'Out of Stock' products in our Product Catalog on a daily basis through Target API Call. I created 2 collections which look at inventory column in the Catalog. I’m also able to query these collections through Postman and get a response back. However current API does not allow to request # of products in each of these collections through the Postman API and I could not find this in the documentation (https://developers.adobetarget.com/api/recommendations/). This will be a great feature to expand the use of Target APIs for something that's of practical use. Thanks!
