[O] can I force all-caps in part of a headline in a capture template?

[Christopher W. Ryan]

I work for a public health department. Twice in the past 5 years we have 
had to open evacuation shelters during a flood, for anywhere from 80 to 
120 medically-frail evacuees. Our documentation system (paper) has 
improved, but it is still not ideal. I am experimenting with whether 
org-mode could meet our needs. It's basis in plain text may strike the 
proper balance between structure and flexibility.

Part of my .emacs includes the following:
(setq org-capture-templates
      '(("a" "Admit" entry
        (file "~/Shelter/ShelterAdmissions.org")
         "* admit  %^{LASTNAME},  %^{firstname} %U
          :PROPERTIES:
          %^{IDnumber}p
          %^{Birthdate}p
          %^{Age}p
          %^{Sex}p
          %^{Address1}p
          %^{Address2}p
          %^{City}p
          %^{State}p
          %^{Zipcode}p
          %^{Doctor1}p
          %^{Doctor2}p
          %^{Pharmacy1}p
          %^{Pharmacy2}p"
          :empty-lines: 1)
          )
)

The first line in my ShelterAdmissions.org file is:

#+TODO: admit(a) in(i!) out(o@) |  discharged(d@)

and things are working pretty well so far.

I'd like to know if there is a way to force LASTNAME to show up in 
all-caps in ShelterAdmissions.org, regardless of how it is typed into 
the capture template.

Thanks.
