No there is no way. But there are simple work around.
The PRS-505 does not directly support Word documents behind the Sony Library software they are converting the Word document to RTF. Sonys PRS-505 RTF support is very limited to reading text only. (No tables, No links, No Images, etc...)
The workaround is to turn your Word document into LRF/ePUB. There are two tools that can easily turn your word document into a LRF/ePUB format.
Both solutions however require
Calibre (see
link)
One is
BookCreator ( download
link) this tool can create an LRF or ePUB and store it directly to your PRS-505 if it is connected.
Simply import the word document and depress the menu option "LRF..." to create the LRF. Enable the "Store eBook To the Sony PRS-505" to also copy it to the PRS-505
The second tool is
WordRMR (see
link).
The latter method will create a LIT file.
1) Import it to calibre
2) Convert it to LRF
3) Copy it to your PRS-505
