Replace file content starts with number) and preserving rest of line content - sed

Question

I would like to replace file contains special pattern with sed or similar solutions. I can replace file with individual sed but number can be anything and need to preserve prefix as it is.
Actual file:
1) L0 | Delete multiple contacts | C543072
2) L1 | Move Multiple Messages via Header toolbar Move button | C1832588
3) L1 | Move Multiple Messages contains file attachment | C2058412
- L1 | Forward message containing attachment | C1976614
- L0 | Normal message contains file attachment | PREAPPS-1488
- L3 | Forward as signed in message view | C1990347
Expected file:
FAILED - L0 | Delete multiple contacts | C543072
FAILED - L1 | Move Multiple Messages via Header toolbar Move button | C1832588
FAILED - L1 | Move Multiple Messages contains file attachment | C2058412
SKIPPED - L1 | Forward message containing attachment | C1976614
SKIPPED - L0 | Normal message contains file attachment | PREAPPS-1488
SKIPPED - L3 | Forward as signed in message view | C1990347
Tried code:
sed -i 's/- L/SKIPPED - L/' /report.txt
sed -i 's/1) L0/FAILED - L0/' /report.txt
sed -i 's/[0-9]) L/FAILED - L[0-9]/' /report.txt (doesn't preserve LX)
Is there any single command using regex to replace content along with preserving LX where string starts with number) L[number]?

Answer 1

Multiple commands in a sed script can be separated by semicolons (;).
$ sed 's/^[0-9]\+)/FAILED -/; s/^-/SKIPPED -/' file
FAILED - L0 | Delete multiple contacts | C543072
FAILED - L1 | Move Multiple Messages via Header toolbar Move button | C1832588
FAILED - L1 | Move Multiple Messages contains file attachment | C2058412
SKIPPED - L1 | Forward message containing attachment | C1976614
SKIPPED - L0 | Normal message contains file attachment | PREAPPS-1488
SKIPPED - L3 | Forward as signed in message view | C1990347
^ matches beginning of the input line,
[0-9]\+ matches one or more digits.
