Hello. Im trying to add multiple dates to a row in a way that the calendar shows each date.
to explain:
I have multiple clients that make monthly payments, and i would like to see the date of each payment on the calendar . For example, client 1 payment today, one month from today etc…
would this be possible? or i need to create a row for each payment?
… And if this is possible, how can i make the form to add the payments, is it possible for automatic calculations? ex. client 1 will do 21 payments, calculate each date per month
thank you in advance

If you don’t have to many fields in the form to add an invoice, I feel that creating a new row for each payment in the easiest approach.

I understand, but i have something like 200 clients, some of them with 21+ payments, i could do a form for each payment, but in terms of work/ time ratio, i would like to avoid it

That sounds to me like the most straightforward approach too. I would resort to Make, loop through the info 21 times to add 21 rows. They have this repeater module that I think would be useful.

But would this add the dates? i mean, would it calculate the date for each month? our would it be better if i somehow try to code it ? the problem for me is that the callendar only has start and finish dates.
I’m sorry, my english is so rusty atm.
Thank you in advance

Yep, when you use the repeater, you can use its value to ride the date calculation.

Say you start with a date of 1st May, then every iteration of the repeater, you can have a function to calculate the date like:
`addMonths(original date; repeater number)`
