Possible Missions Tab

Is it possible to add a funtion to the possible missions tab so that we can search missions based on unit requirements. for example being able to search what missions require ems chiefs, or mobile air trucks. this just helps with determining how many i have. theres no point in having 10 of a unit if the highest required amount on a mission is 1 or 2. yes i get multiple missions but sometimes that space can be allocated for different more needed units.
