AG-Grid server side paging issues -

i looking below 2 features ag-grid pagination. please let me know if possible grid.

1. i have implemented service side pagination ag-grid. pagination gives options "first", "previous", "next" , "last". assume situation having 50 pages. if want go 40th page, have press "next" button 40 times. annoying. there way can specify page number using pagination option?

2. is there way can go particular page during run-time or during grid on ready event?
