A way to heal troops

With the new 1.5 update and the inclusion of the propaganda post and recruitment station I see a niche that has yet to be filled, the healing of troops. All to often during games you will need up with some early game units that have been battered just sitting about on stupidly low hp. While they are healed 15% per day that still means they will have to wait days if not near on a week to become useful as nowdays a low hp until has many many disadvantages. I propose the construction of a building such as a 'field station's (any name will due) that would increase the hp buff to troops at day change or every half day. This wou,d allow a player who values worn troops to replenish them easier but it would require a set up that may not be worth it in many cases. What do you guys think ?
