You can You need to use "Manual score input" on your profile page, it's located on player's profile, little below the scores:Lick wrote:

Now, you need to write in ID of map or link of it. For example, for
Renard - Love Song [insane]
you will need to paste / write either " https://osu.ppy.sh/b/211776 " or just "211776".
The number after /b/ in link is beatmap ID. Don't mistake it with ID or link to mapset, which in this case is https://osu.ppy.sh/s/74617
Also, make sure that you enter correct ID. It happened to me few times that I entered ID of the wrong difficulty. In this case, you just need to enter it again, but this time a correct one^^.
Personally, I am addicted to this button. I don't know, if it's supposed to refresh only from time to time or just once upon visiting your profile, then the next refresh is after X time, but when I play something and I did good, then even if it's within top #1000 on map or top #100 in my scores, I want to see how it affects my profile quickly.
So, I refresh it few times and upon not seeing any change, I just add a play manually. Sometimes I do this quite many times a day
