where to keep DTS from SQL 2000 in 2005 if I don't want to change them

Hi,
reading BOL of 2005 and have few questions about dts and SSIS

question #1
if I don't want to upgrade my DTS to SSIS ,no way I can save it in
msdb of 2005 and I have to do following

1. DTS package have to be  saved as a COM-structured storage file
2. execute  dts as dtsrun /Ffilename /Npackage_name /Mpackage_password

Am I  missing some options ?

question #2
If I want to modify package in 2005 I have to do  following
1. Export package to file from msdb
2. Use Studio to modify and test it
3. Drop package from msdb
4. Import package to msdb from file

Thanks

Alex
