Reinterpreting local function strings in Ghidra (ARM)

Question

The program I'm working with has stuff like this all over:

      strbuf = 0x20746567;
      local_824 = (undefined *)0x6863616d;
      local_820 = (undefined *)0x20656e69;
      local_81c = (undefined *)0x6c696166;
      local_818 = &DAT_000a6465;
                    /* get machine failed */

Here I've added a comment showing what the gibberish actually means. Often when strings are declared in local functions, they look like this, and I type them into an online hex-to-ascii converter to determine what they say.

For what it's worth, this is what the listing window shows:

      0001c1a0 0f 00 ae      stmia     lr!,{ fd r1 r2 r3 }=>strbuf
               e8
      0001c1a4 06 10 a0      cpy       r1,r6
               e1
      0001c1a8 00 20 a0      mov       r2,#0x0
               e3
      0001c1ac 03 00 a0      mov       fd,#0x3
               e3
      0001c1b0 00 c0 8e      str       r12=>DAT_000a6465,[lr,#0x0]=>local_818
               e5

I admittedly have zero experience with assembly, so this means nothing to me, but it may help someone else. I'm also only about a week into my Ghidra experience.

In these cases, is there a way to retype the data so that it shows up in the decompiler as a human-readable string?
