Angular - Select All Checkbox functionality

I am working on the CheckBox functionality where on Click on Select All all the Checkbox must be selected. The problem is data is static and is in HTML file. I have found all other solutions where data is created in ts file and then used as String interpolation in html. However I cannot do that as there are other conditions applied on my html data.

Is there any way I can add Select all checkbox functionality with data in HTML file?

Here is the link to my code - https://stackblitz.com/edit/angular-material-select-all-aota3b?file=src%2Fapp%2Fapp.component.html
