Short PCMCIA USB Card

Ive got a CF-19 Mk4, I use quite oftern a small USB WiFi dongle BUT theres a poss. chance that i'll loose it or forget to remove it, throw laptop in rucksack and damage the USB port

Does anyone know if exists a short PCMCIA USB Card that can be slotted in, the USB WiFi dongle plugged in and the PCMCIA door closed ?

Thanks
