Increase time out of the control panel login

Hello,  Is there a way i can increase the time out of the control panel.  I am migrating 150 sites and have lots of things to do in between but when i go back to control panel after 5 or 10 minutes i am logged out and have to log back in again.  I would like to increase this timeout so have time to complete the tasks that i am working on.

thank you.

This session control by .NetFrameWork itself in the IIS, you can try to extend timing and see if this helps. Go to IIS > Websites > Right click > Properties > Home Directory tab > Configuration Button > Option tab. See the attach pic

Also make same above process on Hosting Controller site too.
