Is there a way to call a block by the block name as a variable?

After showing each page, I want to show a corresponding block on the next page depending on the date information of the responder working on that page. In specific, If DayInfor == Monday, then next show a block named Monday. I will have to do this 'if then' branch for 7 days of a week after each page. Since the embedded data name is the same as the block name. I wonder if there is an easy way to call a block by the block name as a variable. A custom code I am looking for which I can put into JS of a question in that page or in the header is like,
If(DayInfor == Monday)
{
Qualtrics.SurveyEngine.showBlockByName ("DayInfor")
}
Does this API method 'showing block by their name' actually exist? If it does not exist, is there any alternative way to do it? Thank you very much!
