add event page

On the add event page you have:
When, Where, Details etc.
Under Where i.e location you have Address/City/state etc.
Could another field be added here so when creating event a user could enter the venue website from the add event form and that would be added to the location details.? Image below
i am using event attributes for the event which works fine

#_ATT{Website}
#_ATT{Phone Number}
#_ATT{Contact Email}

But would like the location to be able to have a website added without having to go into locations and manually add using location attributes #_LATT{Venue Website}

I amagine some php code in where.php

I did remove REGION ( but can’t remember how i did) i guess i could have renamed that as website instead, if so what was the default code for this, shows in where.php but imagine another reference in another file?
event/location.php i think i removed it so it does not show, so could i put code back and rename?

<tr>
			<th><?php _e ( 'Region:', 'dbem' )?>?</th>
			<td>
				<input id="location-region" type="text" name="location_region" value="<?php echo esc_attr($EM_Location->location_region, ENT_QUOTES); ?>" />
			</td>
		</tr>

change to

<tr>
			<th><?php _e ( 'WEBSITE:', 'dbem' )?>&nbsp;</th>
			<td>
				<input id="location-region" type="text" name="location_region" value="<?php echo esc_attr($EM_Location->location_region, ENT_QUOTES); ?>" />
			</td>
		</tr>
