Customize Ringtone Preference's Ringtone List

Is it possible to customize/control the list of ringtones besides ringtoneType?

For example, to show only the subset of ringtones(in the red box) instead of the entire list.

enter image description here

Currently a RigtonePreference would shows list of ringtones available from my phone, which is filtered by ringToneType:

<RigtonePreference
    android:key="alarm"
    android:title="@string/alert"
    android:ringtoneType="alarm"
    android:persistent="false"
    android:showDefault="false"
    android:showSilent="true" />

Solution

No, you cannot do this.

It is a system provided and populated dialog, and there is no attribute which you can show to filter it to this extent, sorry.
