As a user, I would like to have the option to add Tests and Test Sets when performing a bulk change to a Test Execution without deleting the previous ones

As a user, when performing a bulk change operation for a Test Execution when adding Tests or Test Sets to the field: Change Tests association with a Test Execution
 
it should have the option to not delete the existing Tests associated with the Test Execution in cause and add only the Tests placed in the text box or the datalist box.

Currently, when a user makes a bulk edit of Test Execution tickets, an option is offered: "Change Tests association with a Test Execution". This option allows you to select one or more Test tickets or one or more Test Sets. However, this field applies the "Replace all with" rule, it should offer the possibility to add Tests and Test Sets to the existing ones.
