On Bloomberg, you can do this through the TRACE reporting system, which requires dealers to publish prices soon after completing a trade. A summary of recent price and volume activity can be accessed via Bloomberg using the TDH (Trade History) command. However, this doesn't list down all instruments but mainly gives you a way to analyse the market trend.
In addition to TDH, Bloomberg also provides, Corporate Bond Analysis & Valuation Function (TACT) function via which you can analyse the bonds, it's pricing, marker data along with other indicators. As you would already know, Bloomberg HELP is always available instantly if you need any further information on these commands.
Last but not the least, the FINRA MarketData provides this and other related information on its website, and is quite useful. It also provides a way to search for different asset classes using identifiers (e.g. ticker, etc.). Hth.
