How to calculate the remaining progress in Epic level?

Question

I'm trying out the "Advanced Planning" feature of Jira in here

Looks like I'm able to calculate current progress by story points. Is it possible to estimate the progress at the specific "future" point in time?

I've known that the burn down chart would be the possible way. However It seems only for task / subtask and user story points during the sprintQuarterly, at what time and at what percentage, I wanted to track this at a glance
I made something using JIRA advanced planning function.
It's all good, but the most important information I want to see at a glance is How to know what percentage of Epic A will be completed at the end of January and what percentage of Epic B will be completed at the end of February?Is there anyway to calculate the these specific "future" point in various EPIC level? without any 3rd party solution like "BigPicture"

The Advanced Planning feature in Jira https://www.atlassian.com/software/jira/features/roadmaps. does not currently support estimating progress at a specific future point in time for epics. However, you can use the burn down chart to get a general idea of how the epic is progressing and make an educated guess about its completion date.

To do this, you can create a burn down chart for the epic by filtering the chart to only show issues that belong to the epic. The chart will show you the total story points for the epic and how many story points have been completed over time. You can then use this information to estimate the epic's completion date.

For example, if an epic has 100 story points and 50 story points have been completed, then the epic is 50% complete. If you assume that the epic will continue to be completed at the same rate, then it will be completed in another 20 days. However, this is just an estimate, and the actual completion date could be earlier or later.
