Default duration in calls [mobile app]

Hi,
I managed to change the default duration of calls in the web application to 5 minutes (date_start and date_end fields). I need to know if it is possible to do the same for the mobile app. I couldn't find this information in the documentation.

Changes made:

• custom/modules/Calls/clients/base/views/record/record.php
  • Changed step property from "30" to "5". This modification change the intervals of time that these fields show in their dropdowns.
• custom/modules/Calls/clients/base/views/create/create.js

  • initialize: function (options) {
    this._super("initialize", [options]);
    this.on("render", this._setDefaultDateEnd, this);
    
    },
    
    _setDefaultDateEnd: function () {
    var dateStart = new Date(this.model.get('date_start'));
    var dateEnd = moment(dateStart).add(5, 'm').format();
    this.model.set('date_end', dateEnd);
    },

These changes worked for the web application. Is it possible to accomplish the same for the mobile app?

Thanks!

Regards.
