Scripting option to automatically login on ISP landing page

Hello all,

I have been looking all over to find a solution to the following problem I have:
Firstly, I am using Mikrotik, RB411. Winbox v3.14 and have hotspot usermanager running to cap my users with a data transfer limit.
I would like to step to a new ISP, however this ISP has a general PPPoE account, which then redirects you to a landing page, where you (Like usermanager) login to gain acces to the internet. I would like to know if it is possible to make a script which adds in the login information for me every time a user tries to make an internet connection. I don’t want to bother my users with first a loginscreen for my router, and then a login screen for my ISP.
I can give additional information about the ISP if someone has an idea of solving this problem.

Thank you very much!
