How to add Sitemap.xml File does not include all Links for Large Blogger with 10.000 Posts

Hi All, I’m running a web site from 2012 and having approx 10,000+ blog posts.

As recently done sitemap implementation by blogger team, they added few of i mean first 2500 post urls in sitemap.xml by default
and
Blogger Team must focus on users who having more than 2500 posts, you can see your blogger site map using yourblogURL.com/sitemap.xml 1 which contains

sitemap.xml?page=1
sitemap.xml?page=2
sitemap.xml?page=3
sitemap.xml?page=4
sitemap.xml?page=5

I did’t see more than that in any other blogger sitemaps

and each page Contains 500 posts and all together 2500 post urls may index when you update yourblogURL.com/sitemap.xml 1 in webmaster tool

In this case for time being i Have done a tricky work which can be submit manually for remaining posts

Try as Following

For First 2500 posts: Just Submit yourblogURL.com/sitemap.xml 1 and its enough
for more posts Just keep on add
