Weapon selection missle fix

When using some aircraft that get stock missiles, when you get the modification of the same missile (ie r60m on the mig-29, aim-9l on the f-15) the weapon selection selects both sets of the same missile (changing weapon selection would go r60m-r60m-r27ER, instead of r-60m-r27ER) Can we change it so the weapon selection combines the same missiles together? It can be a problem in battle when you want to switch missiles but end up selecting the same missile again.
