(Use case) Can I loop 'Send push message' in a bot, in order to push multiple URLs to multiple LINE group / room?

Hi. I'm a UX Designer with bare minimum experience working with APIs. I'm currently designing and mapping out a solution for a certain company and I have a question regarding a very specific use case:

• Company A onboard Client#1 by creating and joining a LINE Group using their official account.
• Client#1 then proceed to use Company A's service (externally)
• Company A and Client#1 then proceed to have conversations regarding supports / services wise inside the LINE group.
• At the end of each month, Company A then wishes to charge service fees toward Client#1 by sending an invoice URL with it's own QR payment embeded inside the Invoice into the LINE Group.

The problems / questions are:

• IF it becomes a multiple clients scenario, can Company A then use a bot to 'loop' push Invoice URL message towards multiple LINE groups with Group ID as an identifier?
• If it is indeed possible, are there any request limits / limitations?
• if it's not at all possible, are there any alternatives you can recommend? as most of the Company A's clients already familiarized with communicating through LINE already...

Appreciate the assistance.
