Browser cache access plus setting for multimedia and fonts

Hi,
When I enable browser cache, rules are correctly added to the htacess file. Although, multimedia or fonts files expires is currently added as “access plus 1 month” and I would like to have that setting added as “access plus 1 year”

If I manually modify htacess file, that setting is overwritten each time I save Swift Performance Lite configuration. Is there any way to set “access plus 1 year” from plugin interface?

Thanks
