Adding option for setting the default height/width of the logo

Is there a possibility to add 2 fields in the System Settings (near the logo) which would be used to set the max-width and max-height of the logo itself?

To change this for example:

#invoice-logo { 
max-width: <?php echo invoice_logo_width; ?>em !important;
max-height: <?php echo invoice_logo_height; ?>em !important;
margin-bottom: 1em;

Also I’ve noticed that the invoice_helper.php does not set the id of the invoice_log, but only of the invoice_logo_pdf.
