Hyperlinks master page

I have 30 pages derived from a Master page (INDESIGN 2024), with 12 hyperlinks set in the Master page for 12 objects. Therefore, the 30 pages have the same hyperlinks. I want to change one character in these hyperlinks, knowing that the 12 hyperlinks on the first page are different from those on the second page by one character (for example: the 12 hyperlinks on the first page are www.example.com/1111.... and on the second page www.example.com/2111....) by changing only one character between the pages
