Multi Select from drop down in Journey Task

Summary:

We are trying to have client be able to select multiple options from the drop down in 1 go instead of having to click again and again on the field to enable drop down and then select the options one by one. How can it be made possible? (Screenshot attached below for reference)

Content (please ensure you mask any confidential information):

As you can see in the above screenshot, multiple options can be selected in one field but to do that, we have to click multiple times within the field to enable the drop down menu from which we will go ahead in selecting the option. We are willing to remove that click where we have to click just to enable the drop down and we wish to be able to select multiple options in 1 go.
