How to prevent angular material mat-menu from closing?

I'm creating a date time picker control in the angular material and having the below code to do that

<button mat-button [matMenuTriggerFor]="menu">
<mat-icon>date_range</mat-icon>
<span>Date Range</span>
</button>
<mat-menu #menu="matMenu">
<div fxLayout="row">
<div fxLayout="column">
<button (click)="setInterval(15)" mat-menu-item>Last 15 minutes</button>
<button (click)="setInterval(360)" mat-menu-item>Last 6 hours</button>
<button (click)="setInterval(1440)" mat-menu-item>Last 24 hours</button>
<button (click)="setInterval(2880)" mat-menu-item>Last 2 days</button>
<button (click)="setInterval(10080)" mat-menu-item>Last 7 days</button>
<button (click)="setInterval(-1)" [matMenuTriggerFor]="dateTimeMenu" mat-menu-item>Custom</button>
</div>
<mat-menu class="date-range-menu" #dateTimeMenu="matMenu">
<div fxLayout="row">
<div fxLayout="column">
<b>From</b>
<mat-calendar></mat-calendar>
</div>
<div fxLayout="column">
<b>To</b>
<mat-calendar></mat-calendar>
</div>
</div>
</mat-menu>
</div>
</mat-menu>


Currently when ever I click a button it is closing the menu. I know we can do $event.stoppropagation() on each mat-menu-item to prevent it from closing.

But I want to know is it possible to do that for mat-calendar



As you can see in the above image currently when i select a date it is closing the menu. Is it possible to prevent that?
