There are, but explanations have been given why it's not a good idea.
If keeping the schedule straight is the problem, maybe this will help...
Pick a day of the week. I use Sunday because that's when I do most of the reptile cleaning & maint. chores. On a wall calendar, mark alternate Sundays (or whatever day you choose) with either a
V (Vitamins) or
D3 (Calcium w/ D3). I mark the entire calendar ahead so I don't forget or confuse which supplement to use as the months progress.
On Sundays, dust with what's on the calendar. Every
other day, dust with Calcium w/o D3.
