no there is no simple way.
if they were never in use, then you can archive right away.
if they are used in data, then this data has to be archived first, that is just the way it is.
you cannot expect to get the goods from ebay before you have won the bid.Everything has its logical order, just deleting data leaves inconsistencies in your system and I guess this is a bigger issue.
I actually would ask what is wrong that your users use materials that is marked for deletion.
Did you create duplicates and they do not know which one to use? Did you delete the wrong materials, materials that are still in stock and have still demand from the market?
The match codes can be amended (new match code, or making use of the user exit in the search helps) to hide materials that are marked for deletion.
Set the material and sales status to restrict the usage, see my blog: Material master deletion flag and blocking activities
