Auto jump to an Anchor point when scrolled

Hello Team,

When we scroll on a web page which has 3 Anchor points.
It would be amazing to have a feature which enables us to link the scroll to jump between the anchor points.

Example:

When the user is at the AnchorPoint-1, when scrolled down it has to jump from AnchorPoint1 to the AnchorPoint-2. On further scroll down it has to jump form AnchorPoint-2 to AnchorPoint-3.
similarly when scrolled up, it has to jump form AnchorPoint-3 to AnchorPoint-2.

This feature would be really helpful.
Thanks in advance.
