Custom page in P6 R8.2

Hi all,

Can we plugin custom pages in P6 to allow user to enter data and then use web services to save that data in the database. Here I am taking about large volume of data like Project UDFs (atleast 100 udf at a time) which are mapped to financial periods spread across the entire duration of the project.

I will be using BPM and P6 event for the purpose but still want to explore if there is a possibility to plugin our own custom pages to enter data in P6.

Thanks,
Sachin Gupta
