IMDB credits

Hi everyone,

i hope you are all well. I am new to IMDB. In 2012 I was given a IMDB credit but this was at a time where I was new to the acting business. It is a background credit however it is under a different stage name. Since now J have finally actually created my IMDB page, I want to add that same credit to my credits list however, I want ti deleted from the stage name I had in 2012. is there a way to somehow delete my credit and add it to my new page under the stage name I use now. 
sorry if this question sounds confusing. Please let me know and I will explain further. 

thanks so much

Raggy
