Dynamically updated bookmarks are not currently in the plans. This feature currently only exists on Android, but may not exist in the new rewrite of the Android version which will bring it more in line with iOS. iOS version also doesn't have this feature. It can be tricky to do without the ability to read a user's mind.
However, it is very easy to update your bookmark to your current reading location using the bookmark menu. In fact, we just released a new update to the Beta version which exposes a button making it easier to find the update bookmark feature.
