De-construct naval bases

When a player or the AI builds the naval base at a location that doesn't seem to make much sense from a tactical or strategic perspective, I sure wish I could deconstruct it and put it where I would like it.

For example, I just took Havana, Cuba and the AI put the naval base on the south side of the island. I would prefer it if I could relocate the naval base to the north side of the island so that I can use the embarkation boost to take Florida.
