Farming: Ability to better control planting

So i really like farming at the moment, but one thing bothers me: that i am not able to manually check and uncheck the "plant" command. Usecase for me would be eg corn, which has 50% growth in spring and fall, 100 in summer. So i want them to start planting in spring, but to stop planting after summer (so that maybe at end of summer planted corn can grow out in fall, but they wont plant new ones in mid-fall that wont have a chance to grow fully for harvesting). I dont need a full-blown interface to set this, but just being able to uncheck "plant" would help a lot (No idea if there is a reason we cant though).

Edit: Maybe i am overthinking this, and later on it doesnt really matter cause you have a ton of seeds, but in early game this can be important imo... :D
