Google Sheets | Reference all tabs with a specific word in the COUNTIF statement

Basically, I try to create a main tab that adds up all the data from all the other tabs. These tabs are weekly distribution numbers for ad statistics numbers. A new tab is added each week. Here is what each tab looks like. enter the description of the image here The only option I think about doing this is to add the new tab name to the (write) formula each time I create a new tab. However, I wonder if there is a way to reference all tabs containing a hyphen "-" because they all have a title with a date range separated by a hyphen. Is there any way to succeed that? Maybe even with some kind of support column on the main tab to create? Thank you in advance.
