It can easily be done in LaTeX, by defining macros that contain the
dates and titles and then using those more than once. You can do this in
LyX, too, therefore, using ERT, but there's no native support for it.
Yes there is native support for macros in lyx, but the name is misleading; they
are called Math macros. [Menu | Insert | Math | Macros] will allow you to
define the macro, in both LaTeX and how it should appear in LyX if you so
desire. Then, to use it in your text, insert some Inline Math; type your macro
name preceded with a back-slash.
The downside to this is that they are math macros, rather than simple
LaTeX macros. There's an open bug about providing general macro support.
