What you have in mind would require a bit of custom scripting on your end. The coding would have to manually done as the online button creator has limitations. You may also want to look at Payments Pro, it's also more flexible than Standard.
Should I infer then that PayPal deducts a monthly subscription payment on the same day of the month on which the subscription was initiated? In other words, if the client signs up for a monthly subscription on the 10th of the month, then automatic payments are deducted on the 10th of every subsequent month?
I've searched and searched the PayPal documentation for an explanation of when the auto-payments are processed but have found no explanation.
How Subscriptions with Monthly Billing Cycles Work for Payments Standard. (Pro is controlled by you.)
For monthly billing cycles, recurring payments are collected on the same day of the month. If the initial recurring payment falls on the 31st, PayPal eventually adjusts the billing cycle to the 1st of the month. If the initial recurring payment falls on the 29th or 30th, PayPal adjusts the billing cycle to the 1st of the month on the following February.
When Monthly Recurring Payments Are Due and Collected on the 31st
The subscription terms are:
$25.99 USD a month; the subscriber signs up on Thursday, July 31.
The subscriber is billed as follows:

Saturday, August 31 = $25.99 USD
Wednesday, October 1= $25.99 USD
